The whole crew here at Gadling loves sending postcards. Heck, we love receiving them, too. Sadly, handwritten notes – including postcards – are nowhere near as popular as they used to be. Why send a postcard from the road when you can instantly Skype or IM with someone? Why send one stock photo when you can upload all of your own pictures? The answer to both questions is the same: sending someone a personalized, analog message shows that in that moment, at that place, you were thinking of them and wanted to put some effort into showing them just that. Thankfully, there’s a new iPhone app that combines the thoughtfulness of postcards with modern social networking. Postagram allows iPhone users to turn pictures from the Instagram app into real postcards.Our friends over at TechCrunch shared the info on Postagram earlier today. For just 99 cents, users can turn any one of their Instagram photos into a postcard, add a 140-character message and have it printed and in the recipient’s hand in 2-5 business days (longer for international shipping). Users can do everything from the Postagram iPhone app or on the Postagram website. The picture can even be popped out of the postcard if the recipient just wants the image without the message.

We think this is a great tool for sending postcards to friends, especially if you’re in a location where finding a post office is challenging. And the price is cheaper than the cost of buying a postcard and a stamp in many places.

Certainly there are downsides. The 140-character limit means that you can’t write much of a note to accompany the picture. Also, while it does save the addresses that you enter to mail Postagrams, we’d love to see it access your iPhone’s contacts to make selecting recipients and inputting their addresses that much quicker and easier. Lastly, since it won’t be mailed from your location, it lacks the mystique of postmarks from faraway lands.

That said, it’s still a unique image that you took and chose to share with someone. In that sense, it still maintains the personal feel of postcards.

Anyone who signs up today will receive their first Postagram for free, which is a nice way to try out the app and service. I just made my first Postagram (for free, since I signed up today) and it was quick and easy. Oddly, while their site says that the Postagram will arrive in 2-5 days, the app itself said that it would take 3-7 days. That’s certainly something to keep an eye on.
